As a 20 year owner of a 4 voice with programmer (regrettably sold), one of the MOST AMAZING things to do was stack all 8 oscillators up on 1 note. I would tune them Root (osc 1) 5th (osc 2). Then for each of the remaining 3 voices do the same thing except an octave higher each time. It was MASSIVE. Listen to THE MESSAGE by STYX (Pieces of Eight) to hear a 4voice doing this. I could easily nail this exactly on my 4 voice with unison.

I agree with everyone else asking for voice UNISON and Voice restriction.

Voice number restriction would be great to emulate the 2 and 4 voice SEMs while also taking care of CPU reduction as a side-effect.

UNISON with selectable number of voices being used would also be great, so one could still have 2 or 4 voice polyphony while using 4 or 2 voice UNISON, besides the 8 mono mode.If, besides global unison detune, there was a per-voice detune, kinda like CS-80, that would be even better, I guess (which would emulate SEM OSCs de-tuning on 2x, 4x and 8x setups)

These 2 features would really improve this already great Arturia synth

Yes! UNISON !! AND along with UNISON, the Voice Allocation Modes (FWD,BWD, FWD BWD, RND) could also include a PRIORITY Mode where voice allication always uses the LOWEST card available. So card 1 always sounds first, then card 2, then 3, etc. Then, after the keys are released, and the next key pressed starts with card 1 again, unlike the FWD mode that continues to step through all the cards.

Ability to use a "HOLD" pedel controller for overall sustain would also be nice.
